Specification of Letters Patent.

Patentedl Jan. 1o, Y191i.

To all whom 'it may concern: v

Be it known that I, DAVID E. PARKER, a citizen of the United States, residing atrNiagara Falls, in the county of Niagara and State of New York, have invented a new and useful Device for Generating and Admin-i istering Oxygen, of which the following is a specification.

This Ainvention relates to an inhaler or respirator intended primarily for use by physicians and others to generate oxygen and administer the same to patients in the treatment of certain diseases.

The invention has for one of its objects to provide a device of this character which is of comparatively simple .and inexpensive construction, reliable yand `efficient in use, and so designed as to facilitate thel generation and administering oxygen to patients.

Another object of the invention is .the provision of an oxygen generator in which oxone briquets are used to generate the oxygen .by the action of water thereon, the generator being so designed that the supply of water to the oxone can be adjusted .according to the Ldemand for oxygen, so that when no oxygen is required, the ,supply of water rz will be automatically cut olf to thus prevent waste of the oxone, and while, when oxygen is being administered, the supply .of water is automatically maintained to generate the oxygen as needed. y A

A further object is the employmenhf in connection with a generator ofthis character, of one or more washers whereby the impurities are removed from the gas before being administered to the patient.

With these objects in view and others,y as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangementy of parts which will be more fully described hereinafter and set forth with particularity in the claims append-ed hereto.

In the accompanying drawing,

n, illustrates one embodiment of the invention,

j manufactured from sodium peroxid treated Figure 1 is a central vertical section offvthe device. Fig. 2 is a horizontal section on line 2-42, Fig. l. a

Similar reference characters are employed out the views.

The apparatus is intended primarily for generating oxygen from a compound known commercially as oxone, which is which in anv electric furnace for eliminating, y'to' a large extent, the impurities inherent in the peroxid such as carbonio acid gas. And

after 'being so treated, the material is molded into briquets for.` the market. This oxone is readily acted on by water, so that the oxygen is liberated and can be used for medicinal or other purposes. As the oxygen contains impurities pfalkaline character, the `gas passed through one or more washers jfor removing the impurities, and as the action of 'the water on the oxone is quite rapid, the generator is so designed that only a small quantity o'f water can feed to the oxone, so that an unnecessary waste of the latter is prevented.

Referring to the drawing, A designates the oxygenA generator which, preferably,

consists. of a tank or reservoir 1 of any approved ffyorm such as a jar, in which is contained an oxygen generating chamber 2 in the form of a `bell having a neck portion 3 normally closed by a stopper 4, and the neck portion of the bell 2 has an annular flange 5 which forms a closure for the reservoir l. fThe reservoir is formed with a contracted neck v6 for receivin the closure 5 which l rests on an internal ange 7, and surroundingtlienclosure 5 isa packing 8 for preventing the escape of air or gas. The lower end ofthe bottlefshaped inner section 2 of the generator'is `open and is provided with a perforated or foraminons diaphragm 9 which is held in place by a split ring 10 whereby the diaphragm can be raised or lowered, as

desired.l This diaphragm supports the oxone briquet-S11 which are inserted through the neck 3 of the inner section of the'generator and are acted on by water which rises through the open bottom ofthe inner section'of the generator and perforations of the diaphragm, the water being containedinthe reservoir' 1 in which the lower end of the oxygenchamber 2 is submerged. The reservoir/l1, is only partially filled so that an air space is provided to permit the pressure of the oxygen within the' chamber 2 andpres'- sure `of air in the reservoir, to become equalized.

The oxygen is conducted away from the inner chamber 2 through a tube 12 connected with a nipple 13 formed on the neck 3 at a point above the closure 5, andthe oxygen is passed through one or more wash* are jpreferably, although not necessarily', formed integral with the reservoir 1. These washers contain water through which the oxygen is passed for eliminating the impurities. y The tube 12 is connected with a pipe 14 passing through a stopper 15 in one of the washers and extends downwardly through A the water to a point adjacent the bottom,

and in the stopper 15 is a shorter pipe 16 Which-is connected by a hose or other tube 17..with an inlet pipe 18 of the other washer which is carried by the stopper 19 thereof, andthe oxygen, after passing through the water in the second washer, finds exit through the outlet pipe 20 inthe stopper 19. This pipe is equipped with a fiexible hose V21 that carrlesa mouth piece vor cap 22 which can be placed over the patients mouth and nose so as to inhale the oxygen. The liberation of the oxygen from the oxone creates considerable pressure, so that it readily passes through the washers without much diminution in pressure so that it can be conveniently applied to the patient. i

In case it is desired to 'increase the supply of oxygen, as where it is necessary 1 j to resuscitate the patient, a device is provided to increase the pressure of air in the reservoir so that more water will feed to the oxone and hence the generation of oxygen will be accelerated. Forthis purpose, an

- air pump in the form of a bulb 23 is provided which is connected by a tube 24 with a nipple 25 formed on the closure 5 of the reservoir. By compressing the bulb 23, the

pressure of the air in the reservoir can be increased so as to depress the annular col- -f off the flow of oxygen. The tube 24 can be equipped with a similar device 28 for closingthe tube. The stopper 4 carries an agitator for loosening the oxone crystals from the diaphragm 9 so that water can always have free access to the oxone through the diaphragm. This agitator is in the form of a rod`29 which passes through the stopper 4 and has its lower end formed into a horizontal arm 30 and its outer end formed j into a grip 31. The agitator can'be thrust inwardly to engage the diaphragm and then given one or more turns to loosen the crystals.

When the device is not in use, the valve or device 26 is closed so that there will be no waste of oxygen, the valve 26 being closed immediately afterv the administration of oxygen to the patient. The pres Asure of the oxygen is retained in the chamber 2 and re-acts on the water so as to force the latter downwardly below the diaphragm and away from the oxone so that the generation of the oxygen will cease. This means that the air pressure in the reservoir and the oxygen in the chamber 2 will bc equalized. As soon as the valve 2G is again opened to administer oxygen, the pressure in the chamber 2 will fall so that the water will rise through the diaphragm and act on the oxone so as to liberate oxygen, and as soon as this takes place, the pressure in the chamber 2 increases so as to check the infiow of water and prevent any more than the required amount to act on the oxone. It will thus be seen that the feed of water to the chamber 2 is controlled by the variation in pressure of the oxygen in the latter and the air in the reservoir. Obviously, by increas ing the pressure of air in the reservoir, by manipulating the bulb 23, the supply of Water to the oxone is increased so that. a greater supply of oxygen is created. By reason of the fact that the water is caused to recede from the oxone as soon as the escape of oxygen is stopped, the device can be set aside almost indefinitely without any oxone being wasted and the device is always ready for use, and it is merely necessary toppen the oxygen discharge pipe to permit the oxygen held in the chamber 2 to pass off and thus allow water to enter the chamber for again continuing the generating process.
